Supercar Completes High Speed Test Runs

American supercar company SSC successfully concluded the first round of high-speed testing on Thursday, March 22nd in its quest to break the world production speed record.
Despite encountering some unforeseen obstacles, the Ultimate Aero TT ended the session with a 230mph pass at just 56% throttle in 6th gear.
SSC was forced to move to an alternate location after the original 12 mile high-speed testing site was hit by an unanticipated snowstorm.
An inspection of an alternate site, located 30 miles north at a lower elevation, revealed that just 2 of the 9 miles set aside by the Nevada Department of Transportation were usable.
Dips, cracks, and an exaggerated road crown on the 2 lane highway rendered the other 7 miles unsuitable for high speeds.
The testing session confirmed the stability that the Ultimate Aero TT demonstrated at NASA’s Langely wind tunnel, which had previously shown the car stable up to speeds of 273 mph.
During Thursday’s session, test equipment verified that front to rear downforce percentages and drag coefficients were well within the engineering specifications set by the figures posted at Langely.
SSC made successive 220 mph passes throughout the day and culminated with a 230 mph run just before the 2pm road closure deadline.
A laser speed trap positioned 440ft before the 2 mile marker confirmed the speeds.
SSC test driver Rick Doria stated that the 1183 hp Ultimate Aero TT had “a lot more to go” at 230 mph and was confident that the remaining power and proper road conditions would propel the car past the Bugatti Veyron’s 253 mph top speed record.
The crew spent the remainder of the afternoon scouting potential sites for the next round of testing.
Though SSC hopes to run the second session within the next 2 weeks, their participation at Top Marques Monaco may delay the second test until after the event.
